I think sodium bicarbonate could be work, but this is in the summery Wet your skin with pure water constantly during the day put a very little amount of baking soda in it. Do you have a job? pure water? is this really needed, can`t you use normal water? and the coconut oil, do you really need exactly coconut oil?
I`ve tried it 2 times because i believe it could be work for me. But SD will be to bad so i can`t go on.
